Compared with the traditional vehicle interception technology, the wheel binding mechanism can penetrate the wheel running to the top cover of the binding mechanism through puncture, and the wheel is firmly pulled through the puncture barb, so that the wheel can reach a static state relative to the wheel binding mechanism under the puncture pulling force and the top cover limiting effect. The vehicle body has inertia, when the wheels are fixed by the wheel binding mechanism, the inertia of the vehicle body can drive the wheel binding mechanism to continuously slide forwards, and the wheel binding mechanism generates static friction force on the ground through four elliptical wheels, so that the bound vehicle body is blocked to the maximum extent; the wheel binding mechanism controls the swing amplitude of the puncture through the inertia of the punctured wheel, and then controls the resistance of the front driving shaft and the rear driving shaft through the transmission structure, so that the resistance of the driving shafts and the ground resistance of the elliptical wheels are balanced, and the static friction between the elliptical wheels and the ground is always ensured, so that the wheel binding mechanism generates the maximum resistance to intercept the vehicle; since the drive shaft is subjected to a great pressure, the drive shaft is first supported and fixed by the drive shaft support, and then the stabilization sleeve support serves the purpose of stabilizing the drive shaft. Wherein the transmission between the puncture and the elliptical wheel is as follows: the pressure rods, the pull rods, the inclined blocks and the slide rails on the two sides of the puncture constitute two crank slider structures, the puncture swings around the puncture rotating shaft, the puncture swings to pull the pressure rods on the two sides, and the inclined blocks slide in the slide rails through the transmission of the pull rods; the puncture rotating shaft is a punctured swing rotating shaft, the pressure lever and the puncture are connected together by the rotation of the pressure lever around the swing rod, the pressure lever is connected with the pull rod by a cylindrical pin between the two side blocks, and the pull rod is fixedly connected with the inclined block; inclined planes are arranged on the inclined blocks on the two sides, and the sliding of the inclined blocks enables the adjusting plate supported by the inclined planes on the inclined blocks to move up and down; the adjusting plate is fixed with the pressing sleeve through the lower spring support, and the pressing sleeve moves up and down under the combined action of the movement of the inclined block and the pressing spring; the up and down movement of the adjusting plate changes the friction force of the pressing concave surface on the pressing sleeve to the driving shaft. The installation positions of the first inclined block and the second inclined block are completely symmetrical, before the wheel runs to the top cover, an included angle of 60 degrees is formed between the puncture and the top cover, the direction points to the direction of the wheel running into the top cover, at the moment, the puncture is inclined, the positions of the inclined planes of the inclined blocks on the two sides, which are contacted with the adjusting plate, are different, the upper end of the inclined plane of the second inclined block on the wheel running side, which is contacted with the adjusting plate, is positioned at the upper end of the inclined plane, and the lower end of the inclined plane of the first inclined block on the other side, which is contacted with the adjusting plate, is arranged at the lower end of the inclined plane, but the designed driving shafts on the two sides are subjected to the same resistance, namely, when the puncture is inclined by 60 degrees, the sliding rail support on the wheel running side is longer than the sliding rail support on the other side, so that. When the wheel drives into the top cover, the puncture pierces into the tire, the tire is prevented from rotating by the puncture, the puncture is driven by the tire to swing for an angle in the process, the faster the vehicle speed is, the larger the bending degree of the pressure lever is, the larger the swing angle is; after the puncture swings for a certain angle, the inclined blocks on the two sides start to slide, the adjusting plate on the second inclined block starts to move downwards, and the adjusting plate on the first inclined block starts to move upwards, so that the resistance of the driving shaft on the driving side of the wheel is greater than the resistance of the driving shaft on the other side; the design reduces the possibility that the wheel restraining mechanism turns forwards, namely the resistance of the rear driving shaft in the wheel restraining mechanism in the driving direction of the automobile is larger than the resistance of the front driving shaft. The design of the inclined surface of the adjusting plate is adapted to the inclined surface of the inclined block, so that the inclined surface is in surface contact with the adjusting plate, and the friction loss is reduced.

The design of the elliptical wheel aims to know that the larger the wheel is, the larger the friction force to the ground during braking is, the better the braking performance is, and under the condition that the height of a wheel binding mechanism is limited, the larger the friction force of the elliptical wheel in contact with the ground is, so that the elliptical wheel is more beneficial to stopping a vehicle; in the design of the elliptical wheel, the telescopic inner rod, the telescopic outer sleeve and the support lug are driven by the driving shaft to drive the rubber ring to rotate elliptically, the guide groove slides on the elliptical track, the distance between the guide groove and the center changes along with the elliptical track at any time, and the telescopic inner rods of the telescopic outer sleeves are mutually nested to adapt to the elliptical track in motion; after the rubber ring is driven, the rubber ring is connected with the elliptical track through the middle support lug and the side support lugs, the position of the side support lug where the rubber ring is installed makes elliptical motion, and the rotating rubber ring is constantly in deformation in the rotating process so as to adapt to the elliptical track. In the sliding process of the guide groove on the elliptical track, the included angle between the position of the side support lug on which the rubber ring is installed and the connecting line of the center of the ellipse changes in a small degree, so that the designed telescopic inner rod is installed in the ring groove of the driving shaft through the inner rod swing shaft to adapt to the purpose of changing the small degree between the telescopic inner rods. The balance wheel arranged on the driving shaft plays the roles of auxiliary driving and support reinforcement, and is embodied as follows: the telescopic inner rod penetrates through the swing hole or the clamping hole in the balance wheel, the swing hole is larger than the telescopic inner rod, the telescopic inner rod can move in the swing hole, the swing hole cannot interfere small-amplitude swing of the telescopic inner rod, the size of the clamping hole is basically consistent with that of the telescopic inner rod, the telescopic inner rod penetrating through the clamping hole is limited to swing in a small amplitude, and the telescopic inner rod penetrating through the clamping hole is designed to drive the rubber ring to rotate in the whole process. Although the telescopic inner rod which swings at a small angle can drive the elliptical wheel, the driving force fluctuates due to small change of the angle between the telescopic inner rods; therefore, a fixed telescopic inner rod is selected to drive the elliptical wheel to reduce the fluctuation of the driving force and assist the driving of the elliptical wheel. The short diameter position of the elliptical wheel is in contact with the ground, the upper side and the lower side of the elliptical wheel are both short diameters, the nesting degree of the telescopic outer sleeves and the telescopic inner rod is the largest at the two positions, the telescopic outer sleeves extend into the radial surface of the balance wheel towards the center side, and the balance wheel strengthens the rigidity of the structures of the telescopic outer sleeves and the telescopic inner rod at the upper side and the lower side through the radial surface. Therefore, the balance wheel is designed to achieve the purpose of strengthening the structural rigidity on the upper side and the lower side of the elliptical wheel, and limit the swing of the telescopic inner rod to achieve the purpose of assisting in driving the elliptical wheel. The design of the inclined plane is beneficial to the telescopic jacket extending into the balance wheel.

When the automobile wheels pass through the wheel binding mechanisms, one wheel only acts with one independent wheel binding mechanism, and the wheel binding mechanisms under the wheel tension are taken away by the wheels without influencing other wheel binding mechanisms, so that the subsequent vehicle to be intercepted is disabled; when the wheel crosses two adjacent wheel binding mechanisms, the two wheel binding mechanisms move forwards together under the pull force of the same wheel. The invention uses the wheel binding mechanism to bind the wheels, quickly brakes the automobile without damaging the automobile, assists the public security organization to stop illegal vehicles, and has better use effect.

In summary, the wheel restraining mechanism 70 of the present invention can penetrate the wheel traveling on the restraining mechanism top cover 35 through the puncture 40 and can be pulled by the barb of the puncture 40, and the wheel will reach a static state relative to the wheel restraining mechanism 70 under the pulling force of the puncture 40 and the limiting effect of the top cover 35. The vehicle body has inertia, when the wheel binding mechanism 70 fixes the wheels, the inertia of the vehicle body can drive the wheel binding mechanism 70 to continuously slide forwards, and the wheel binding mechanism 70 generates static friction force on the ground through the four elliptical wheels 38, so that the bound vehicle body is blocked to the maximum extent; in the wheel binding mechanism 70, the swinging amplitude of the puncture 40 is controlled through the wheel inertia of the punctured 40, and then the resistance of the front driving shaft 10 and the resistance of the rear driving shaft 10 are controlled through a transmission structure, so that the resistance of the driving shafts 10 and the ground resistance of the elliptical wheel 38 are balanced, and the static friction between the elliptical wheel 38 and the ground is always ensured, so that the wheel binding mechanism 70 generates the maximum resistance to intercept the vehicle; since the drive shaft 10 needs to be subjected to a great pressure, the drive shaft 10 fixing firstly uses the drive shaft support 51 to fix the drive shaft 10, and secondly the stabilization swivel support 50 serves the purpose of stabilizing the drive shaft 10. Wherein the transmission between the puncture 40 and the elliptical wheel 38 is: the pressure lever, the pull rod, the inclined block and the slide rail 62 on the two sides of the puncture 40 form two crank slider structures, the puncture 40 swings around the puncture rotating shaft 45, the puncture 40 swings and pulls the pressure lever on the two sides, and the inclined block slides in the slide rail 62 through the transmission of the pull rod; the puncture rotating shaft 45 is a swinging rotating shaft of the puncture 40, the pressure lever and the puncture 40 are connected together by the rotation of the pressure lever around the swing rod 48, the pressure lever is connected with the pull rod by a cylindrical pin between the two side blocks, and the pull rod is fixedly connected with the inclined block; the inclined blocks on the two sides are provided with inclined planes 29, and the sliding of the inclined blocks enables an adjusting plate 64 supported by the inclined planes 29 on the inclined blocks to move up and down; the adjusting plate 64 is fixed with a pressing sleeve 68 through a spring lower support 66, and the pressing sleeve 68 moves up and down under the combined action of the inclined block movement and the pressing spring 37; the up and down movement of the adjustment plate 64 changes the friction of the pressing concave surface 65 of the pressing sleeve 68 against the driving shaft 10. The first inclined block 54 and the second inclined block 61 are installed at completely symmetrical positions, before the wheel runs to the top cover 35, the puncture 40 and the top cover 35 have an included angle of 60 degrees and the direction is towards the direction of the wheel running into the top cover 35, at this time, the puncture 40 is inclined, the contact positions of the inclined surfaces 29 of the inclined blocks at two sides and the adjusting plate 64 are different, the second inclined block 61 at the wheel running side and the adjusting plate 64 contact the upper end of the inclined surface 29, the first inclined block 54 at the other side and the adjusting plate 64 contact the lower end of the inclined surface 29, but at this time, the designed driving shafts 10 at two sides are subjected to the same resistance, that is, when the puncture 40 deviates 60 degrees, as shown in fig. 17, the slide rail support 69 at the wheel running side is longer than the slide rail support 69 at the other side so as to ensure that under the condition that the action heights of the inclined blocks at two sides are different, the pressing sleeves 68, to ensure that the drive shafts 10 on both sides are equally pressurized by the pressure applying concavity 65. When the wheel drives into the top cover 35, the puncture 40 pierces into the tire, the tire is prevented from rotating by the puncture 40, the puncture 40 is driven by the tire to swing by an angle in the process, and the higher the vehicle speed is, the larger the bending degree of the pressure lever is, the larger the swing angle is; after the puncture 40 swings for a certain angle, the oblique blocks on the two sides start to slide, the adjusting plate 64 on the second oblique block 61 starts to move downwards, and the adjusting plate 64 on the first oblique block 54 starts to move upwards, so that the resistance of the driving shaft 10 on the driving side of the wheel is greater than the resistance of the driving shaft 10 on the other side; this design reduces the possibility of the wheel restraint mechanism 70 tipping forward, which corresponds to the rear drive shaft 10 of the wheel restraint mechanism 70 being subjected to a greater resistance in the direction of travel of the vehicle than the front drive shaft 10. The design of the inclined surface 29 of the adjusting plate 64 is adapted to the inclined surface 29 of the inclined block, so that the inclined surface 29 and the adjusting plate 64 are in surface contact, and friction loss is reduced.

The elliptical wheel 38 is designed for knowing that the larger the wheel is, the larger the friction force to the ground when braking is, the better the braking performance is, and under the condition that the height of the wheel binding mechanism 70 is limited, the larger the friction force of the elliptical wheel 38 in contact with the ground is compared with that of a common circular wheel, so that the elliptical wheel is more beneficial to stopping the vehicle; in the design of the elliptical wheel 38, the driving shaft 10 drives the telescopic inner rod 7, the telescopic outer sleeve 6 and the support lug to drive the rubber ring 5 to rotate elliptically, the guide groove 20 slides on the elliptical track 8, the distance between the guide groove 20 and the center changes along with the elliptical track 8 at any time, and the telescopic inner rod 7 of the telescopic outer sleeve 6 is nested with one another to adapt to the elliptical track 8 in motion; after the rubber ring 5 is driven, the rubber ring 5 is connected with the elliptical track 8 through the middle support lug 4 and the side support lugs 3, the position of the side support lug 3 where the rubber ring 5 is installed makes elliptical motion, and the rotating rubber ring 5 is constantly in deformation in the rotating process so as to adapt to the elliptical track 8. In the sliding process of the guide groove 20 on the elliptical track 8, the included angle between the position of the side support lug 3 where the rubber ring 5 is installed and the connecting line of the center of the ellipse changes in a small range, so the designed telescopic inner rod 7 is installed in the annular groove 27 of the driving shaft 10 through the inner rod swing shaft 28, and the purpose of adapting to the small-range angle change between the telescopic inner rods 7 is achieved. The balance 9 mounted on the drive shaft 10 acts as an auxiliary drive and support reinforcement, embodied as: the telescopic inner rod 7 penetrates through the swing hole 31 or the clamping hole 32 in the balance wheel 9, the swing hole 31 is larger than the telescopic inner rod 7, the telescopic inner rod 7 can move in the swing hole 31, the swing hole 31 cannot interfere small-amplitude swing of the telescopic inner rod 7, the clamping hole 32 is basically the same as the telescopic inner rod 7 in size, the telescopic inner rod 7 penetrating through the clamping hole 32 is limited to swing in a small amplitude, and the telescopic inner rod 7 penetrating through the clamping hole 32 is designed to drive the rubber ring 5 to rotate in the whole process. Although the telescopic inner rod 7 which swings at a small angle can drive the elliptical wheel 38, the driving force fluctuates due to the small change of the angle between the telescopic inner rods 7; therefore, the fixed telescopic inner rod 7 is selected to drive the elliptical wheel 38 to reduce the fluctuation of the driving force and assist the driving of the elliptical wheel 38. The short diameter position of the elliptical wheel 38 is in contact with the ground, the upper side and the lower side of the elliptical wheel 38 are both short diameters, the nesting degree of the telescopic outer sleeve 6 and the telescopic inner rod 7 is the largest at the two positions, the telescopic outer sleeve 6 extends into the radial surface 30 of the balance wheel 9 towards the center side, and the balance wheel 9 strengthens the rigidity of the structures of the telescopic outer sleeve 6 and the telescopic inner rod 7 at the upper side and the lower side through the radial surface 30. Therefore, the balance 9 is designed to enhance the structural rigidity on the upper side and the lower side of the elliptical wheel 38, and limit the swing of the telescopic inner rod 7 to assist in driving the elliptical wheel 38. The design of the ramp 29 is advantageous for the telescopic jacket 6 to project into the balance 9.

When the automobile wheels pass through the wheel binding mechanisms 70, as shown in a in fig. 18, one wheel may only act on one independent wheel binding mechanism 70, and the wheel binding mechanism 70 subjected to wheel tension is taken away by the wheel without affecting other wheel binding mechanisms 70, thereby causing a failure effect on a subsequent vehicle to be intercepted; as shown in fig. 18 b, when a wheel crosses two adjacent wheel restraining mechanisms 70, the two wheel restraining mechanisms 70 are pulled by the same wheel to move forward together. The invention uses the wheel binding mechanism 70 to bind the wheels, quickly brakes the automobile without damaging the automobile, assists the public security organization to stop the illegal vehicle, and has better use effect.
